How to use Regex with ng-repeat in AngularJs?

I want to use regex in ng-repeat. I have tried the following code but its not working.

<div ng-repeat="user in users | filter:{'type':/^c5$/}"></div>

I have users array and I only want to display the users with type c5.

If I use

filter:{'type':'c5'} 

then its displaying the users with type "ac5x" too, because its contains c5.

How can I solve this problem? Maybe there is another solution.

Thank You!
